XL Fortran for Linux

IBM® XL Fortran for Linux is a standards-based, high-performance Fortran compiler with advanced optimization and performance-tuning features. It enables the development of parallel applications that exploit the latest IBM POWER8® processor with multi-core and vector features. XL Fortran for Linux optimizes your infrastructure on IBM Power Systems™ in support of extensive numerical, scientific and high-performance computing.

IBM XL Fortran for Linux delivers

A single XL Fortran offering for both big endian and little endian Linux distributions.

Leading-edge optimization and performance tuning technology that takes advantage of hardware advancements in Power Systems™, including the latest IBM POWER8 technology.

Basic Linear Algebra Subprograms (BLAS) consists of libraries of high-performance algebraic functions, performing combined matrix multiplication and addition on general matrices or their transposes, and compute the matrix-vector product for a general matrix or its transpose.

Profile-driven optimization

Profile-directed feedback optimization collects information about a program run with typical input data and then applies transformations to the program based on that information.

Profile-directed feedback can ensure the performance of the application is optimized for its important inputs.

Supports a subset of Technical Specification 29113 for further interoperability of Fortran with C.

Helps to protect investments in existing Fortran source and object code built with previous versions of the compilers, allowing users to rebuild and link all the components into the same applications using the latest compiler versions.

Supports compatibility of object code or libraries compiled with previous versions of XL Fortran with the newest XL Fortran compiler and runtime environment.
